[R] plot

[Rene Braeckman]

You can do something like this for a scatter plot:

x <- c("a","b","c")
y <- c(1,2,3)

xnum <- rep(1:length(x))
plot(x=xnum, y=y, xlab="x", xaxt="n")
axis(side=1, at=xnum, labels=x)

This fakes a numerical axis and suppresses the y-axis labels that you then
draw with the axis function the way that you want them. If you play with the
xnum vector, you can have different spacing of the points in the
x-direction.

Subject: [R] plot

Hello sir:
a data with 2 columns:
id x
a  1
b  2
c  3

I wanna get such kind of plot:
x: a b c
y:1 2 3

But the plot command doesn't permit string character as x.

How can I get it ?

Thanks a lot !

My best
